In order to even possibly recover HD files, it requires someone with the special tools and software to do so. Check your local computer repair businesses.

Need a bit more information. PC or Mac? Any other files showing corruption? What error message are you receiving?

As a start, if it’s a PC, you might consider running chkdsk from the command prompt. Just type chkdsk? for the proper syntax.

This should NOT happen, but it also makes the point of backing up your files. More information on what kind of computer you're using and what error messages you're receiving would be helpful.

The computer is Windows 10 machine. The message is files are corrupted. I run checkdsk and sfc /scannow.

I periodically back up to a separate storage, but it is not practical to check all files before doing so. Thus, when I find the problem it is usually too late or the problem is already propagated to the backup storage.

So, what I am asking is if there is any way or utility software to repair corrupted image files.

I've never had to do this. I see this on the internet. https://recoverit.wondershare.com/computer-problems/restoring-corrupt-files.html

One other thought. Are the files still on the card in your camera? I never get rid of mine, contrary to the advice of some on this forum (Waste of money not to reuse them. Sorry, I'm paranoid.)

I have successfully used Recuva on solid state drives where the FAT / Inode table was trashed, but not in your specific circumstances. Any chance you have Windows restore points enabled so you can revert the file system to a point before the corruption? I'd also be very interested in finding out how the files were corrupted. I'm guessing that Windows virus definitions and patches are up to date and you've run something like spybot. All that being the case, I'd be checking the disc controller and HDs with every diagnostic you can muster before it happens again. Some NAS devices and file systems utilize snapshots to allow you to revert the FS to an earlier point in time. No help now, but something to think about for the future. Good luck!

An excellent idea if one is lucky enough to have very recent restore points, and this requires that system restore be turned on to begin with. Some software will turn it on and create a restore point to go back to when you install it. Some Windows updates will do the same. The default is to not have it turned on, so although it is a good idea to check, it may not be possible.

Yep, I think my Win 10 installation had it disabled on installation, and I had to enable it. When I worked for NetApp (Network Appliance), one of our big selling points was that our file system (WAFL) incorporated snapshots to address this exact type of failure (a corrupted file or file system propagates to the backup, making the backup useless).

Windows "Restore" ignores data ....
only refreshes operating files.

Looked it up. Good point.

I am recycling memory card otherwise I have to keep purchasing cards. Besides, it is not convenient to manage files in a card saved in an extended period. Also using a big capacity card is risky because memory card can fail.

User guide of recoverit from Wondershare indicates it can not repair damaged files. I tried a trial version and it could not.

Restore point can not be of any help as responded by TriX. Restore point will undo only changes in OS system including application softwares.

Thanks for the clarification - I should have referred to Windows File History functionality which I believe allows reverting to previous versions of the user’s files/documents. (https://support.microsoft.com/en-us/help/17128/windows-8-file-history). Probably no help to the OP inhis current circumstance, but useful for future prevention of the issue when backing up data.

I keep purchasing cards. My choice. My used cards are kept in a safe place away from my other backups. My choice.

My cards are not my primary means of backup. My primary backups are multiple external hard drives (in triplicate). Sooner or later, I'm going to burn all of my pictures onto MDisks. 1000 year shelf life. Call me paranoid if you will.

I had a problem with one of mY CF cards. My 5dmk4 has two slots. i record RAW on the SD, jpeg on the CF. I had about 20% of the jpegs corrupted, with rainbow streaks across the picture. I use PS CC. I was playing around with the card and stumbled on being able to open the pictures uncorrupted. so try using a different software package.
I didn't do much later as I had the Raws. By the way, it only happened wit 1 CF card, not another one i have, so i discarded the card. I have no issues with the second CF card I use.
